You should never connect classified and unclassified systems together. True or False.

• A. True
• B. False
• C. It Depends
• D. Not Applicable

Answer: (A)

Keeping classified and unclassified systems separate is essential for protecting sensitive information. Directly linking these two environments creates an unprotected path for threats to move from less-secure networks to more-secure ones, increasing the risk of malware, data leakage, or unauthorized access to SCI. Segregation helps enforce strict access controls, need-to-know, and thorough auditing, so classified data cannot flow onto unclassified networks accidentally or maliciously. In practice, any data transfer between levels must go through formal, controlled processes that sanitize and review the information, rather than a continuous network connection.
